I am currently "assessing" a JSP application. I am no jsp expert, i have some experience in jsp with jsf development only. I suspected that the technology of this application was in very old j2ee. Is there anyway to find out the detail version, technology, or platform from source code? Or roughly how old of the jsp version is this application? For following is some the ui code. Please take a look, i find it that it's ridiculously complicated compared with current jsp and jsf platform.

<jsp:include page='header.jsp'></jsp:include>
  StringBuffer htmlBuffer = new StringBuffer();
 // get viewbean interface and cast it to view bean object accordingly
 com.nihb.mtrd.bean.AdminVB vb = 
 //display message if there is any
 String message = vb.getMessage();
 if(message == null){ 
  message = new String("");
 htmlBuffer.append("<p><b><font face='Verdana' size='1' color='#cc0000'>");
 htmlBuffer.append( message );
 htmlBuffer.append("<div align='center'>");
 htmlBuffer.append("<table border='3' cellspacing='0' style='border-collapse: collapse' width='800 ' cellpadding='0' id='AutoNumber7' height='9' bgcolor='#E8F3FF' bordercolor='#E8F3FF'>");
 htmlBuffer.append("<TR><td width='800' height='7' colspan='8'>");
 if( vb.getIndicator() != 0){
  htmlBuffer.append("<a href='MtrdHome.jsp?mysubmit=");
  htmlBuffer.append("' >");
 htmlBuffer.append("<b><font face='Verdana' size='2'>Change Password</font></b>");
 if( vb.getIndicator() != 0){


thanks all!
